To Quito it may concern:

Be it known that l, G. Dor a citizen of the United States, residing stDeyton, in the county of Montgomery end State of Ohio, haveinvented'certsin new end useful Improvements in Machines for CuttingMost, of which the following is e specifica- Lion.

My invention relates to machines for cutting meat and similar articles,the object of theinvention being particularly to provide emeohine foraccurately slicing meets into 1 slices -of the desired thickness orthinness,

themochine being one which is simple in its construction and effective moperation, all of; the parts being readily accessible for cleaning andthe driving mechanism being so formed that 1t Wlll operate freely andeesily parts being shown in section. Fig. 4 is e detail View of themechanism for giving the step-b -step movement to the slide. Fig. 5 is aetail view of the pawl arm. Fig. 6 is a sectional view of the gear andconnection between the fiywheel and o crating shaft.

Like parts are indicate by like letters of reference throughout the sevrel views.

The frame of the machine is indicated by A and the platform by a. Thisplatform is pivoted at a, (Fig. 2) and is capable of on oscille'tinmovement, as will be more fully explained The platform carries itdownward projecting support, a', and an arm, 09. The free end of theerm, a slides over a bearing: surfece or track a on the main frame A.(See Fl 3). The main anointing shaft is in'dicetediy a (See Fig. 6,.This shaft is rigidly secured at one end to the crank arm, a", whichfurnishes means for continuously rotating the o crating shaft, a

Thissheit is journaled oosely mthe frame supports, A, A, and at itsother end has rigidly secured thereto. a rotary cutter, a Intermediatethe irzrme supports, A'- .153,

there is a gear connection to the fly-wheel,

ing shaft, or". The large gear wheel, a", is rigidly secured to theshaft, and an interimdinte gear, a, is loosely journelod on a. stud,

a, PIOJCClJflg from one of the frame suports A. The gem, a, is connectedto e. erger gear, a, which in turn meshes with a larger gee! wheel, 11.,ourualod loosely on the shaft, and rigidly secured to the lly wheel, aConsequently, when the main operating shalt rotates the cutter, 1.1. andthe gear a rotates therewith, the motion of the shaft will betransmitted to the ill wheel, a, through the intermediate goers,

a a and a at e uuich higher speed.

The main shall, a, is provided with a sprocket wheel, a, and a sprocketchain, a, connects said main shaft to the sprocket wheel, 0;, (Figs. 6end 1), which sprocket. wheel is connected to a gear, a, by it shaft, iwhich gem" is shown in mesh with the gear, a, secured rigidly to e.shalt, d sold gear, al being rigidly co.u;1 .ectod to a pinion, a". Each01" the snelts (I? end it are suitably supported and journnled on themain frame A. The pinion, a3, is prefers.hly formed with teeth of alarge 'oitch adapted to en gage with e series of pins or studs forminga. rack, of. The shaft, d", proferui ly extended beyond the pinion, a soas to engage in a com track, a, formed in the arm, a, which carries therack, 0, The arm, a, is pivoted to the table at a, so that it will movewith the table but can rise and fell to permit the rock to be raisedebove or depressed below the pinion, a, and thus produoe it back andforth movement of the arm and table, as before stated.

The end of the arm, 0,, carries the track, a), (see Fig. 2, end therock, e is located centrally of this track so that when the pinion, 11continues its revolution, the pinion will force the mm, (1 dmvmvardlyend will lie on the upper pert ol. the reels, a until it reaches a. mintopposite thet shown in Fig. 1 when t 1e arm, of, will be elevated by theend of the shaft, (11 (Fig. 6) and the pinion will lie on the lower portof the track and by the moshing with the ruck re urn the table to normal1' osition-thc position shown in F ig. 2. During this oscillating movement of the table, the 11 rojecting support, (L3, will slide upon thebearing surface, a, and 11love shown the opening in the arm, a, throughwhich the support, if, passes,

sufficiently large to permit the arm, a, to have necessary verticalmovement. (See Figs. 2 and 3). The connections for transmitting movementfrom the fly-wheel to the slide, 0, which is sup orted on the table a inorder to ive the shdb a step-by-step movement is illustrated in Fi s. 2,4 and 5. It is further to be understoo that the slide, 0, is adapted tosup ort the article to be cut, and has a step-lFy-ste movementsufiicient to feed the article to t e cutter. In order to hold thearticle securely on the slide, 0, I have shown an upright b, (Fi 3) uponwhich is pivoted a pressure arm, i, formed with projecting pins, b Thereis a pawl, 6 pivoted to the arm, 6, adapted to en age the rack, 6 formedin the lower art 0 the arm, I), and b placing the artic e, such as meat,on the s ide, 0, so that the article will rest upon the pins, 6?,thereon the arm, I), can readily be set so that this article will beheld securely on the slide. In order to give the pro er step-by-stepmovement to the slide, I have shown a awl arm, I)", (Fi s. 4 and 5).This arm is oosely su porte on the end of the upright shaft, Ii (Fig. 3)which shaft is sup )orted within the housing, I)", (Fig. 4), and thishousing is formed integral wlth the table a. To the lower end of theshaft, 1) is rigidly secured a ratchet wheel, I)", ant on the upper endof the shaft is rigidly secured a pinion, b, (Fig; 3). A s ring-pressedpawl, 12, (Fig. 5) carried on the pawl arm, engages the ratchet wheel,I), and when the pawl arm, I), is advanced thepawl, b, will advance theratchet wheel and the pinion, b, will be correspondingly moved. The pawlarm, I), carries at its one end a step, b", which stop is ada ted tolimit the retracting movement of t e pawl arm. A spring, I) (Fig. 4)normally holds the pawl arm inretracted position, and the a; is 'oscill'awl' arm and gear, pinion, s ring indred parts, are all carried by t etable, a,

'returnedsto normal y will retract the paw stop, I), will be thrownagainst the projectin support ,b which projects from the ta la a aholding awl, b, on said support reventing the rate et wheel 7;, fromturning. t-is apparent from this description that th;

and movable with the table.

' -There'is' pivoted a sector-shaped piece, 0

to the stationary frame, A, of the machine, and apin, '0, projectsupwardly from said pie'ce,,c, 1n the path of movement of the pawl arm.b. Consequently, when the table ated, the end of the arm, 6, willstrike the pin, 0, and the arm will be advanced to a limited extent,'thereb partially rotating the pinion, 5 When t e table is position,thespring, 6, arm, I), to its normal position.

1 In Order to vary the amount of the movement iven the pinion, b", b thepawl arm, h I ave shown a pivots sector-shaped eiae're pressed pawl, c,(Fig. 2) is employed to prevent the return movement of t e ratchet, I),and pinion, 6 thereby insurin an inter mittent advancing movement 0 theslide. Bythis construction I have connected the fly wheel and shaft withthe table and slide so that by the continuous rotating movement of thefly-wheel and shaft there 15 transimtted an oscillating movement to thetable and a step-by-step movement to the slide,

tgefiutter, a", being operated directly by the s a The table in itsmovement back and forth is supported immediately under the point wherethe cutting is done by a roller, (1, which is preferably mounted on asupport, (2, on the main frame. This gives the table a very ri idsupport while allowing it to move freely ack and forth, the sup ort'being located just at the-point where th s pressure would come againstthe table from the out tinlg operation.

t should be noted also that all of the arts, including the fly-wheel andthe cranl r are located above the bottom of the main frame so that thedevice as a whole can be placed upon a counter or any other supportwithout any qveiihangm parts to interfere. t ,will be on erstood thatthe adjustment in the step-by-step movement of the slide to seizure athin or thicker cut is secured by moving the;sector, c, to differentositions indicated by the graduated sca e. This moves the step, c, todifferent positions in the line of travel of the pawl arm, I), so thatthe said arm will contact with said step sooner or later as the tableoscillates,,-;i),nd' thus produce a greater or less movemer'l of the armand consequently of the slide. Means are provided for securing thesector in different ositions of adjustment as shown at 0 As s own in thedrawings, particularly Fig. 2, the pivotal point of the ta do is shownporting roller, a main operating shaft, a

cuttin blade secured directly to said shaft, a flywheel, an intermediategear connection between the fi'y-wheel and shaft to cause said fly-wheelto revolve at a greater speed than said shaft, a movable arm on saidtable carryin teeth or projections in the nature of 9. rec a imonadapted to be engaged on op osite s1 es by said rack to cause said tableto ocsillate from a continuous movement of saidpinion, and means fordriving said pinion continuously from the movement transmitted from saidmain shaft, substantially as specified,

'2. In a meat cutting machine, the combination of a table capable ofoscillating movement, an arm carried by said table, a rotating shafthaving a cutting blade, teeth on said arm, a pinion adapted to engagesaid teeth, and means for causing said arm to moveto opposite sides ofsaid pinion, connections from said shaft to said table, and means forsupporting said table adjacent to the meeting point between said bladeand table, as specified. 3. In a meat cutting machine, the combibinationof a table capable of oscillating movement, a pivoted arm projectingfrom said table, teeth on said arm, a pinion adapted to engage saidtooth, and means for causing saidarm to bomoved to a position above andbelow said pinion. to causcthe teeth to be engaged on opposite sidesthereof, arotating shaft carrying a cutting blade, means for imiartingmotion to said shaft and blade, and a connection from said shaft to saidpinion, as and for the purpose specified.

4. In a meat cutting machine, the combination with a notaryknife and anoscillating table, an arm carried. b said table and adapted tomoverigidly with said table in its oscillating movement but pivotedthereto to permit a vertical movement of said arm, a rack carried bysaid arm, a pinion to engage said rack, said pinion being connected tothe driving connection of said knife, and a cam-track operating inconnection with said )inion to cause said arm to be raised and epressedto bring saidrack above and below said pinion, res ectivelv, to secureoscillating movement 0 said table.

5. in. a. meat cutting machine, the combination of a rotary knife andits driving mechanism, of a pivoted table adapted to oscillate in frontof said knife, a fly-wheel mounted loosely on the shaft which carriesthe knife, and a driving connection between said shaft and saidfly-wheel to cause said fly-wheel to rotate at a-greater speed than thespeed of said knife, a otary pinion under said table, means forimparting rotary movement to said pinion from said driving mechanism, apivoted arm carried by said table, and means for causing said arm tomove vertically above and below said pinion, and teeth on said armadapted to be engaged by said pinion and from opposite sides thereof tocause said table to oscillate from the continuous rotary movement ofsaid inion, substantially as s eciiied.

6. in a meat cutting machine, the combination of a supporting table, aslide on said table, stationary projections on said ivoted arms mountedon saidslide and slide in a ane at right-angles to the lane of saidslide, said pivoted arms eing adapted to project over the stationaryprojections and provided at their opposite ends with a segmental ratchetand pawl to hold them in different positions of adjustment.

7. The combination with the oscillating table, a slide thereon, a rackon said slide and a pinion mounted on said table, means for impartingmotion to said pinion which comprises a ratchet-wheel and a sprinpressed pawl-carrying arm, a stop on sai pawlecarrying arm to engage apro ection on said table, a movable sector mounted independently ofsaidtable and carrying a stopto engage said pawl-carrying arm, an meansfor'adjusting said sector to produce movements of different lengths ofsaid pawlcarrying arm by the oscillations of said table. 8. Incombination with the oscillating table, a slide having astationaryprojection and the pivoted arms with ratc et teeth above saidslide, a series-of teeth on said slide and a pinion mounted on saidtable to engage said teeth, a tpawl-carryin arm and ratchet also ,mounteon said ta 1e, and a connection between said ratchet and pinion, aspring for moving said pawl-carrying arm in one direction and aprojection adapted to engage said arm and move it in the oppositedirection when said table is oscillated, and means for adjusting themovement of said pawl-carryin arm, as specified.

In testimony w ereof, I have hereunto set my hand this 18th day ofMarch, 1907.
